I immediately jumped to and agree with the part on Domain-based structure:
We still need artefacts like models, views, and controllers, whichever way we lay out the code, but grouping them by [MVC] type should not form the primary structure. Instead, the top level of the codebase should show the primary use cases of hospital management; maybe
patient_history,appointments,staffing, andcompliance.Taking a domain-based approach to the code structure makes it easy to understand what the code is there for, and easy to navigate to wherever you need to be for anything more complicated than “make that button light blue”.
